In a study of sleep patterns of babies a researcher reported the following results for the number of hours per day the babies slept from randomly selected babies: 13.3 12.8 12.6 14.3 13.3 12.2 12.7 12.7 12.2 12.8 12.6 Construct a 99% confidence interval for the true mean number of hours a day babies sleep, assuming the data is normally distributed.
